Description

Portable air purifier
Technical Field
The present invention relates to a portable air cleaner having a compact size so as to be easily installed in an indoor space of a vehicle, an office, or the like, and more particularly, to a portable air cleaner in which an outer case has a long length so as to have a predetermined length in an up-down direction, contaminated air flowing into a lower side of an inside of the outer case is primarily cleaned by a high efficiency particulate air filter, and the primarily cleaned air is rotatably raised along an inner peripheral edge of an outer cover by an impeller and uniformly passes through a photocatalyst filter positioned above, so that dust or the like is not easily accumulated in the inside, sterilization and cleaning efficiencies are high, and not only a replacement operation of the filter is simple, but also the impeller provided in the inside can be separately coupled to an upper cover in an integrally detachable manner, thereby facilitating a cleaning and washing operation, and the like.
Background
Recently, the air environment is seriously affected by the increase in the number of automobiles, the densification of factories, the high-rise phenomenon of buildings, apartments and the like, and it is difficult to normally breathe in the outside with the rapid increase of fine dusts.
Vehicles traveling on roads are urgently required to prevent the inflow of the above-mentioned fine dust, block ultraviolet rays, and maintain a suitable state in a room.
During driving, bacterial particles of dust, dirt, pollen, etc. present in the road and sulfur dioxide SO present in the polluted air2Nitrogen compound NOXAnd various harmful substances such as carbon monoxide CO, etc. flow into the interior of the automobile.
In particular, when a heater or an air conditioner is turned on in cold or rainy weather, malodor and bacteria particles generated at this time directly flow into a vehicle interior called an interior flow field, thereby causing discomfort to a driver or a passenger.
In this way, the air conditioner for a vehicle is equipped with a filter for supplying purified air to the driver or passenger by preventing the bacterial particles or harmful substances from flowing into the vehicle interior.
However, the filter cannot completely purify harmful substances and fine particles such as yellow sand.
On the other hand, in order to solve the above problems, a portable dual-purpose air cleaner that can be used in vehicles and general households is disclosed in korean laid-open utility model publication No. 20-2012-0005357 (published 24/07/2012), a "portable dual-purpose air cleaner", which is a prior art.
Referring to fig. 1, the "portable air purifier" of the related art will be described, the portable air purifier including: a suction port 110 for sucking air; an exhaust port 120 for exhausting air; a power button 130; a blower fan 200 for sucking air through the suction port 110 and discharging the air to the exhaust port 120; a main body case 100 provided with an anion generator 400 for discharging anions together with air discharged to the air outlet 120; and a bracket 500, wherein the main body case 100 is detachably formed on an upper surface of the bracket 500, and a lower surface of the bracket 500 is selectively attached to and adhered to a vehicle or a home, and the main body case 100 includes a detachable power supply connection part 140 for selectively receiving a power supply for a vehicle or a home to drive the blower fan 200 and the anion generator 400.
However, the conventional "portable air cleaner for dual use" as described above is used only in a place where power is supplied so as to be connected to a charger for a vehicle and an ac adaptor for home use, and therefore, the use is inefficient, and a position where the bracket 500 can be attached to the inside of the vehicle is limited, and therefore, the work of fixing the bracket 500 to a specific position is difficult and complicated, and the bracket is always in an attached state, and therefore, the inside of the vehicle becomes complicated, and an additional attachment and detachment unit, a magnet, or the like is required in order to attach or attach the bracket 500 to the vehicle, and when the bracket is fixed by an adhesive or the like, the adhesive performance of the adhesive is lowered in summer, and thus, a problem that the bracket 500 is detached from the attached position frequently occurs.
Further, the conventional "portable air cleaner used in combination" as described above is a technique for discharging air and anions through the exhaust port 120, and as the air cleaner is used for a long time, there are problems that foreign substances and the like are accumulated in the blower fan 200 installed inside and are not clean, and that the anions and the purified air cannot move to a distant place of the indoor space through the narrow exhaust port 120, and only the periphery of the exhaust port 120 spreads, and appropriate air is slowly circulated in the indoor space.

Accordingly, the impeller 21 sucks contaminated air into the air inlet 11a of the main body case 11, and the air passing through the air filter unit 30 is discharged through the air outlet 13a of the upper cover 13 a.
On the other hand, the impeller 21 includes a flange 21c extending and protruding at a predetermined height so as to form a predetermined internal housing space along the upper side.
In contrast, the drive motor 22 is accommodated in the internal accommodation space inside the flange portion 21c, and the motor shaft 22a is integrally coupled to the central shaft hole 21d of the impeller 21 to rotationally drive the impeller 21.
The fixed cover 23 is connected to an upper portion of the driving motor 22 to cover the driving motor 22 exposed to the upper portion, that is, to cover the internal housing space.
The fixing cover 23 has an opening along the lower side and an edge extending along the lower side, and has a substantially circular cross-sectional shape, a shaft engaging portion 23a formed to protrude toward the center is coupled to the motor shaft 22a of the driving motor 22, the edge is coupled to the fixing cover 23 to surround the flange portion 21c of the fixing cover 23, and the fixing cover 23 is integrally coupled to the impeller 21 and the driving motor 22 to form the blower unit 20.
Therefore, in an embodiment of the present invention, the air blowing unit 20 may be integrally separated and combined in the outer casing 10.
The air filter unit 30 purifies and sterilizes polluted air flowing into the external case 10 through the blower unit 20.
In an embodiment of the present invention, the air filter unit 30 includes a high efficiency particulate air filter 31 and a photocatalyst filter 32.
Referring to fig. 5 and 6, the hepa filter 31 is provided inside the outer case 10, and may be preferably disposed to correspond to the plurality of air inlets 11 a.
The above-described hepa filter 31 is a filter for collecting fine dust in air, and the hepa filter 31 is a filter for collecting fine dust harmful to a human body, and therefore, air passing through the hepa filter 31 is air from which fine dust is removed.
The hepa filter 31 is disposed below the inside of the main body casing 11 so as to be located below the impeller 21, and contaminated air is directly purified while flowing into the inside of the main body casing 11 through the air inlet 11 a.
On the other hand, there is a possibility that the collected fine dust adheres to the surface of the high efficiency particulate air filter 31 into which air flows, that is, the inside of the air inlet 11 a. In this case, in an embodiment of the present invention, when the high efficiency particulate air filter 31 is removed in a state where the lower cover 12 is separated, the inside can be cleaned through the lower opening of the main body case 11, and thus, the adhered or trapped fine dust can be easily cleaned as described above.
Therefore, in an embodiment of the present invention, the hepa filter 31 has a long cylindrical shape.
Referring to the drawings, the particulate air filter 3 is a cylindrical shape elongated in the vertical direction and has a hollow interior, and the particulate air filter 31 is configured to collect the particulate dust and the like flowing in through the air inlet 11a along the outer periphery of the particulate air filter at four sides of the outer case 10. Therefore, as described above, when the high efficiency particulate air filter 31 is separated from the outer casing 10 for cleaning or replacement of the high efficiency particulate air filter 31, the high efficiency particulate air filter 31 remains attached to the air inlet portion of the main body casing 11, and in this case, the lower cover 12 of the main body casing 11 is detachable, so that dust and the like trapped inside the main body casing 11 can be easily removed, and not only the cleaning operation of the main body casing 11 can be performed.
In the above-described hepa filter 31, the lower end portion is formed with the annular lower groove portion 31a, and the lower groove portion is attached to and supported by the attachment portion 12b protruding upward at a predetermined height from the inner side of the lower cover 12, so that the lower cover 12 is separated from the main body case 11 together with the lower cover 12 toward the lower portion of the main body case 11, and the replacement work and the like are extremely simple when the life is up.
The inside cover 40, which will be described later, is connected to and supported by the particulate air filter 31, and includes an annular upper groove portion 31b that is recessed upward in a single direction by a predetermined depth, similarly to the lower groove portion 31 a.
The photocatalyst filter 32 is used to re-sterilize the air first purified by the hepa filter 31.
That is, the photocatalyst filter 32 performs a cleaning and sterilization process again on contaminated air sucked into the outer case 10 by the impeller 21, after passing through the hepa filter 31, before being discharged to the air outlet 12a of the lower cover 12, and in one embodiment of the present invention, the photocatalyst filter 32 is detachable into the upper cover 13.
On the other hand, the photocatalyst filter 32 may be in a form in which a photocatalyst substance is contained in a circular case having a predetermined thickness, and the photocatalyst filter 32 may be integrally formed inside the upper cover 13.
In contrast, referring to fig. 6, an engagement portion 13b is formed along the inner peripheral edge at the lower end of the upper cover 13. Further, the locking portion 13b has predetermined elasticity in the radial direction, so that a user can couple the photocatalyst filter 32 to the upper cover 13 by forcibly fitting, and the photocatalyst filter 32 can be easily attached to and detached from the upper cover 13, so that the photocatalyst filter can be easily detached by holding one end portion and pulling the end portion.
Therefore, in an embodiment of the present invention, when the user holds the upper cover 13 and rotates and separates the upper cover 13 from the body case 11 in a state where the screw is loosened, the photocatalyst filter 32 is separated together with the upper cover 13, and thus, the photocatalyst filter 32 can be replaced and the dust can be removed very easily.
In addition, in the photocatalyst filter 32 according to an embodiment of the present invention, a photocatalyst material may be coated on a base having a plurality of through holes. The base of the photocatalyst filter 32 may be made of a porous ceramic material. Alternatively, the base may be formed of a metal body (Form) containing nickel (Ni), iron (Fe), aluminum (Al), chromium (Cr), or the like. The surface of the base is coated with a photocatalytic material, which may comprise TiO, as described above2、ZnO、ZrO2、WO3At least one of (a). Alternatively, the base of the photocatalyst filter 32 may contain a photocatalytic material.
Thus, in the portable air cleaner 1 of the present invention, not only the fine dust having a size of 2.5 μm or less can be removed by the high efficiency particulate air filter 31, but also the harmful bacteria contained in the polluted air can be removed by the photocatalyst filter 32 as described above.
On the other hand, the portable air cleaner 1 according to an embodiment of the present invention further includes an inner cover 40, which is formed to uniformly pass through the photocatalyst filter 32 by the whirling updraft formed in the outer case 10 by the suction force of the impeller 21, and the air discharged to the outside of the outer case 10 is rapidly discharged to the remote inner cover 40.
In contrast, the inner cover 40 includes a lower guide cover 41 and an upper guide cover 42.
The lower guide housing 41 entirely surrounds the periphery of the blower unit 20, and preferably covers the lower periphery and the side surface direction of the blower unit 20 to form a side surface passage through which a predetermined amount of air sucked by the impeller 21 passes.
Referring to fig. 6, lower guide housing 41 includes a lower through-hole 41a, and a predetermined portion of air inlet 21a of impeller 21 is inserted toward the center of the lower end thereof so that air passing through hepa filter 31 flows into impeller 21.
The lower guide cover 41 includes a flange cover 41b that projects and extends along the lower periphery thereof, and covers a predetermined portion along the outer periphery of the upper end portion of the cylindrical particulate air filter 31.
The lower guide cover 41 includes a snap-in portion 41c formed to protrude downward so as to be spaced apart from the flange cover 41b by a predetermined distance, so that a lower end portion thereof can be forcibly snapped into the upper groove portion 31b formed at an upper end portion of the particulate air filter 31.
Therefore, the lower guide cover 41 prevents air from leaking toward the impeller 21 at the edge portion of the hepa filter 31 due to the structure of the flange cover 41b and the snap-in portion 41c, and air must pass through the hepa filter 31. Further, the lower guide cover 41 can be easily attached to the upper end of the hepa filter 31.
In this case, the lower guide cover 41 has an outer diameter such that an outer peripheral portion thereof can be closely attached to the inner peripheral surface of the main body case 11.
Therefore, in the lower guide cover 41, the air forcibly discharged to the side discharge port 21b by the suction force of the impeller 21 is guided and moved upward through the passage P formed between the blower unit 20 and the inner peripheral edge of the lower guide cover 41, and in this case, the impeller blades of the impeller 21 form a curved vortex surface having a predetermined radius of curvature, thereby forming a whirling updraft in which a large amount of the air sucked is rapidly discharged through the narrow passage of the inner peripheral edge of the lower guide cover 41.
On the other hand, as described above, the air discharged through the impeller 21 is discharged through the side discharge port 21b having a gradually enlarged scroll shape and becomes air having a low pressure and a constant pressure, and thus the impeller 21 of the blower unit 20 operates smoothly without vibration or noise.
The upper guide cover 42 is coupled to an upper portion of the lower guide cover 41 to cover an upper portion of the blower unit 20.
The upper guide housing 42 is provided to the lower guide housing 41 in a state where the blower unit 20, which integrates the impeller 21, the drive motor 22, and the fixed cover 23, is fixedly coupled.
On the other hand, an inner vent hole 42a for passing air rapidly rotated and raised by the lower guide cover 41 is formed along the edge direction of the upper guide cover 42.
The lower end edge portion of the upper guide housing 42 is inserted into the upper end of the lower guide housing 41 and is appropriately coupled thereto. The lower guide housing 41 and the upper guide housing 42 include a plurality of protrusions and groove portions that are engaged with edge portions of each other and supported.
An inner side wall 42b is formed to protrude and extend along a lower portion so as to form a space having a predetermined inner diameter by forcibly fitting and coupling an upper end portion of the upper guide cover 42 to an inner peripheral edge of a lower end of the upper cover 13, and a plurality of locking protrusions 42c having a predetermined elasticity and capable of expanding a diameter of a lower end portion of the inner side wall 42b by a predetermined size are formed on the inner side wall 42b so as to be locked and supported by an end of an edge portion of the fixed cover 23.
Accordingly, in the portable air cleaner 1 of the present invention, the fixing cover 23 of the air blowing unit 20 can be easily attached to and detached from the locking portion 42c of the upper guide cover 42, and on the other hand, when the user separates the upper cover 13 from the main body housing 11, the air blowing unit 20 including the impeller 21 can be completely detached from the inside of the main body housing 11.
Accordingly, the portable air cleaner 1 according to the present invention has the effect that the air discharged from the impeller 21 is rapidly moved in the direction of the air discharge port 13a by the high-speed rotation and uniformly passes through the circular photocatalyst filter 32 provided at the upper side of the inner housing 40, and a large amount of air of a predetermined amount can be discharged to the outside, that is, a corner portion of the indoor space through the air discharge port 13a, due to the structure of the inner housing 40 as described above.
